The Atlas 10k II easily defends its margins in the ZD Disk WinMarks. Its Business score of 8.6 MB/sec is 19% higher than the next fastest unit,IBM's Ultrastar 36LZX. The Atlas' High-End result of 24.6 MB/sec is even more impressive, leading the second-place Fujitsu MAJ3xxx by 23%.

Regular readers are likely aware that we're not very high on WinBench these days. It should be noted, however, that Quantum believes WinBench 99 is still the most accurate tool to measure workstation performance of various disks. This in itself would probably surprise no one since the Atlas 10k II is by far the leader in the Disk WinMarks, easily besting even the Seagate Cheetah X15. What's interesting is that Quantum thus joins Seagate in backing WB99's accuracy. With the current state of affairs, Seagate has far less of an interest in propping up WB99 as #1. After all, the ATA IBM Deskstar 75GXP matches the Cheetah 36LP in the High-End Disk WinMark and beats it in the Business test. At any rate, Quantum and Seagate both acquiescing to WB99 is definitely food for thought.
